The seat in front of the pedestal will then be ad jus-ted as to height by passing" the bolt 5G rearward through the hole 235V, which will all'ord the elevation desired for the pupil using such seat. The nut 52 will then be adjusted and tightened, completing the adjustment and firmly fixing' `the elevation or position of the desk body. The forni of bracket ist with' respect to its two arms and the manner of fitting it to the front cylindrical surface o the pedestal insures maximum rigidity and strength, and yet the entire construction is so designed as to afford maximum ioor space for the janitor when the parts are adjusted, as shown in Fig. 3, givingr ample opportunity for thorough cleaning of the Hoor. Furthermore, there are n0 projecting' angles or corners that are apt to in` jure the children or cause unnecessary wear and tear on Jtheir clothinfr or school supplies. Obviously, the desks and seats are made ot' different sizes; and in connection with the adjustability of the desk and seat portions independently.of each other, it is an easy matter for proper adjustn'ient to be made to suit every individual child, a matter of vastv nnportanee in view of the present and proper demand for correct seating and. desk facilities, for hygienic reasons.
